DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a vehicle body panel, and more particularly to a structure for mounting a roof panel and a roof side rail.

[0002]

2. Description of the Related Art Automobiles have a structure in which a vehicle body roof portion is divided into a general roof portion and a roof side portion in order to secure dimensional accuracy around a side door or to improve the formability of a roof panel. There is.

An example of this will be described with reference to FIGS. 8 to 11. Both sides of a roof outer panel 1 are stepped, and a flange portion 2 extending in a horizontal direction is formed here.

On the other hand, the roof side rail outer panel 3
A vertical wall 4 is formed on the inside, and a mounting portion 5 extending toward the vehicle interior is provided at a lower edge of the vertical wall 4. The flange portion 2 of the roof outer panel 1 is overlapped with the mounting portion 5 to spot-weld the two.

A groove 6 formed at a joint between the roof outer panel 1 and the roof side rail outer panel 3.
Inside, a roof molding 7 is arranged to cover the dents of the spot welding (a similar structure is disclosed in, for example, Japanese Patent Application Laid-Open No. 3-92444).

[0006]

Although the seal lip 8 above the roof molding 7 comes into close contact with both the roof outer panel 1 and the roof side rail outer panel 3, water tightness can be ensured. As shown in FIG. 1, in order to mount the roof bow 9 disposed on the back side of the roof outer panel 1, a flange portion 10 extending horizontally is formed at an end of the roof bow 9, and the flange portion 2 of the roof outer panel 1 and the roof side are formed. It is necessary to sandwich the flange portion 10 between the rail outer panel 3 and the mounting portion 5. Therefore, in order to increase the rigidity of the roof bow 9, it is necessary to increase the plate thickness, which leads to an increase in the weight of the vehicle body.

That is, in the general part of the roof bow 9,
As shown in FIG. 10, even when a cross-sectional shape for increasing rigidity can be adopted, this cross-sectional shape cannot be adopted for a joint portion between the roof outer panel 1 and the roof side rail outer panel 3, and a flat flange portion is used. Therefore, the thickness must be increased to 10 in order to secure the rigidity at the attachment site.

Further, a paint seal 11 is applied to the end of the flange portion 2 of the roof outer panel 1. Since the application of the paint seal 11 is performed in the groove 6,
The application part is difficult to see from the outside and the work accuracy is reduced, for example,
If the amount of application is too large (see FIG. 11), there is a problem that the roof molding 7 rides on the paint seal 11 and raises.

Accordingly, the present invention is to provide a vehicle body panel mounting structure capable of eliminating a roof molding and improving assembling workability.
